The crust is the outermost solid shell of the planet. It is chemically different from the underlying mantle. The scientific name for the crust is the lithosphere. It has an average thickness of 30-35 kilometers in continental areas and 5 kilometers in oceanic areas.
Lithosphere.
Lithosphere
"Lithosphere" is the term given to the rocky outer layers of the Earth. The "Earth's Crust" is another name for the same thing.
There is oceanic crust and continental crust. Oceanic crust is thinner and more dense than continental crust and is constantly being recycled via subduction upon collisions with continental crust, and creation at mid-ocean ridges.Oceanic crust is rougly 3 to 4 miles thick (5 to 7 kilometers). Continental crust is roughly 20 to 30 miles thick (30 to 50 kilometers). The lower density of continental crust allows it to float on the mantle with high relief. Furthermore, oceanic crust is mainly made of basalt whereas continental crust is mainly made of granite.
Very broadly this may be referred to as bedrock. That is the upper boundary of solid rock below any superficial soil deposits. On a whole Earth scale you may be referring to the crust / lithosphere depending on if you were considering earth based on it's chemical compositional layering or it's mechanical properties, whereby the crust is the outer hard rocky layer of the earth that is composed of broadly more silica rich rocks than the underlying mantle which is composed of rocks enriched in iron and magnesium and the lithosphere is the term used to describe that portion of the Earth that behaves as an elastic brittle solid and responds to large stresses by the formation of fractures (faulting) and which combines the crust and the solid brittle portion of the upper mantle.
Lithosphere.
It is called the lithosphere.
If you are using the term 'upper crust' euphemistically and not to refer to bread or pies, then the upper crust is made of aristocrats. If you mean the upper part of the earth's crust, then it is made of the lightest elements from which the planet is made (silicon, aluminum etc).
The lithosphere.
The Earth's crust is also known as the "lithosphere" but that term geologically includes the upper elastic part of the mantle.
This is the Continental crust (also some Oceanic), as the crust part of the Lithosphere.
No.Earth's crust is made of rock.:) __________Get a palatable portion of it, grind it up really well, add it to your favorite recipe or beverage-- why not? Maybe that's where the term upper crust came from...
The crust is the top layer of the earth. Here are some sentences.Earth's crust can be many miles thick.Below Earth's crust is the mantle.Earth's crust is broken into many plates, which shift about on the liquid interior.We live atop Earth's crust.
the term crust is suitable for the layer of the earth we live on because it is the rocks that cooled from the outer core under it.
